“…AOM comprises mainly high molecular weight (MW) organics such as protein-like and polysaccharide-like substances [5] which can cause severe membrane fouling and lead to decrease in membrane permeability [3,4]. It has been demonstrated that the presence of AOM in addition to the effluent organic matter in secondary effluent can further reduce the efficiency of LPM filtration [6,7], thus increasing the operating cost. However, Lee and Walker [8] reported that hydrophobic polysulfone UF membrane could remove 91% of microcystin-LR whereas hydrophilic CA membranes adsorbed little or no microcystin-LR.…”
